First of all, it's not supposed to be a pleasant, nurturing environment, you go there so they can prevent you from killing yourself. To get long-term care to actually address your issues (as opposed to keeping you safe during an episode or safely re-feeding an anorexic on the brink of starvation), you have to check yourself into rehab or start an intensive outpatient program. Of course, Chantal does not have the patience or commitment for a program like that and thinks that a doctor should be able to fix her in a couple days at the ER.
"The actual psychiatry department has like stigma against psychiatric problems." Nobody enjoys treating a demanding narc bitch. Being admitted is an awful, traumatic experience, but it sounds like she was never actually in the hospital and is just salty they didn't take her bullshit seriously. Complaining about how the free psychiatric care is not amazing and can't accommodate everyone/everything is ridiculous. She is not entitled to more help than the people who are in a state of emergency and need those spots, especially when she makes enough money to seek good care. I thought she said she has insurance?
She's complained before about how there's 4-6 beds in the ER, which is dumb but might actually be true. In a general ER, the beds for patients are usually in a couple hallways or something, but what a psychiatric patient needs is not the same as what a patient with say, diabetic ketoacidosis needs. The psych beds must all be in view of a hospital security guard at all times so they're usually in a cluster together. If they tried to fit like a dozen beds in the area one guard can see, the beds would have to be super close together which would mean no privacy at all for the patients (who can't be behind curtains because they must be seen at all times) and they don't want the literally psychotic patients talking or fighting. They keep you in the ER until a bed in a nearby psychiatric facility opens up. These places, despite having more than 6 beds, are usually at capacity but that's where you can be properly assessed and cared for. To avoid not having space for someone who's really in danger, they don't keep you in the ER if you can safely wait out whatever's happing at home. If Chantal wants help she should check herself into a center or hospital because that's where the ER would send her anyway, and if she does that she could choose a good place (and you really want to choose where you go, trust me some of these places are horrible), plus she would get to skip being in the ER.
